Configuring 6lbr for BBB #97

Closed bhayanisunny closed 8 years ago

bhayanisunny commented 9 years ago

Hi,

I am following the below link from TI Wiki to configure the 6lbr as Router using TI CC2531 on BBB: http://processors.wiki.ti.com/index.php/Cc26xx_sw_examples

I am able to run the 6lbr service. But I am not able to see the aaaa or bbbb interfaces.

My network does not support dynamic IPv6 address allocation. So I have modified my /etc/network/interfaces file with the below:

auto lo iface lo inet loopback

iface eth0 inet static address 0.0.0.0

auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_stp off up echo 0 > /sys/devices/virtual/net/br0/bridge/multicast_snooping post-up ip link set br0 address ip link show eth0 | grep ether | awk '{print $2}'

auto eth0

iface lo0 inet6 loopback

iface eth0 inet6 static pre-up modprobe ipv6 address fe80:0:0:0:0:0:a0a:621a netmask 64 gateway fe80:0:0:0:0:0:a0a:6201

The 6lbr.conf is as below:

This file contains a default configuration for BeagleBone platform using

a Telos SLIP Radio

The full list of parameters and their meaning can be found in 6lbr.conf.example

MODE=ROUTER

Bridge Mode

RAW_ETH=0 BRIDGE=1 CREATE_BRIDGE=0 DEV_ETH=eth0 DEV_BRIDGE=br0 DEV_TAP=tap0

RAW_ETH_FCS=0

Enable this line if radio device is not detected

SCAN_DEVICE=/usr/lib/6lbr/bb-scan-usb.sh

LOG_LEVEL=3 #INFO and above only

LOG_LEVEL=5

LIB_6LBR=/usr/lib/6lbr BIN_6LBR=$LIB_6LBR/bin WWW_6LBR=$LIB_6LBR/www

LOG_6LBR=/var/log LOG_6LBR_OUT=$LOG_6LBR/6lbr.log LOG_6LBR_ERR=$LOG_6LBR/6lbr.err

So can you please let me know if I am missing anything.

Below are the logs from /var/log/6lbr.log

Hello,

If you are using a bridge interface, you should not try to configure any ip address on eth0 as they will be deleted when the interface join the bridge. Also, fe80:: addresses are not routable, so you will not be able to reach the WSN network.

Either allow address auto configuration on your BBB (see https://github.com/cetic/6lbr/wiki/6LBR-Connection) or manually assign a bbbb:: address to the br0 interface :

iface br0 inet6 static
address bbbb::xxxx:yyyy
netmask 64
